The music director made the announcement at an event with Bhatt and filmmaker Imtiaz Ali at the Taj Lands End in Mumbai.
“We have this lullaby, ‘Sooha Saha’ in Highway. Imtiaz said Alia has a great voice and I didn’t trust him. Then she learned the song and sang to me and I was pretty impressed with her natural ability too,” stated Rahman.
“We guided her a little bit to perfect the singing. She did it twice and then we got it almost right and now it sounds great.”
Bhatt shares vocals with Pakistani singer Zeb Bangash on the track.
Alia sings very well… what do you think?
